Definitions
- the present disclosure relates to hybrid vehicle drive transmissions which include an electric motor (E-motor) integrated into the transmission, which is located in the drive line between the internal combustion and the driven wheels, to provide drive torque from the E-motor in addition to or in place of the drive torque from the internal combustion engine.
- E-motor electric motor
- Hybrid vehicle drive transmissions which include an integrated E-motor.
- the position of the rotor has to be sensed and the rotor position data signaled to the controller for the E-motor.
- all known electric drives are controlled using a rotor position sensor (RPS) that is located coaxial with the E-motor. This can involve complex and/or custom designed rotary resolvers or encoders to fit in the space adjacent to the rotor or around the torque converter hub that extends from the torque converter outer shell to which the rotor is directly mounted.
- RPS rotor position sensor
- a coaxial architecture is optimal depending on the available space; however, in view of the shrinking space available in hybrid vehicle drive transmissions, alternative solutions may be advantageous for additional space saving as well as reduced costs.
- a transmission with an integrated hybrid drive includes a transmission housing as well as a torque converter rotatably mounted within the transmission housing.
- the torque converter includes an outer shell with an impeller pump configured to be drivingly connected to a crankshaft, and a turbine within the outer shell that is connected to an output shaft.
- An e-motor is integrated into the transmission and includes a stator connected to the transmission housing, a rotor connected to the outer shell of the torque converter, and a controller.
- An auxiliary drive unit is provided having a drive shaft that is driven by a connection to the torque converter outer shell.
- a rotor position sensor (RPS) is provided on the drive shaft that is configured to signal rotor position data to the controller. This arrangement allows for offset positioning of the RPS relative to the axis of the rotor and torque converter, which provides for better space utilization and also allows for a standard RPS to be utilized.
- the auxiliary drive unit is an oil pump.
- the oil pump is preferably located on a side of the transmission housing opposite from a torque converter side, and the drive shaft for the auxiliary drive extends through the transmission housing.
- the RPS is positioned on the torque converter side of the transmission housing.
- the torque converter further includes a torque converter pump hub, and a chain drive extends between the torque converter pump hub and the drive shaft for the auxiliary drive.
- a torque converter pump hub extends between the torque converter pump hub and the drive shaft for the auxiliary drive.
- a drive ratio of the torque converter pump hub to the drive shaft is 1:1.
- the controller can be adjusted or calibrated to compensate for other drive ratios so that the rotor speed is determined.
- the drive ratio could be from 1:2 to 1:6, although other ratios are also possible.
- the RPS is mounted to the transmission housing, and a resolver housing is mounted over the rotor position sensor.
- the resolver housing is sealed to the transmission housing to provide a water-tight enclosure for the RPS. This is a requirement for some transmissions that have specific wet running capabilities.
- the transmission may further include a flex plate that is drivingly connected to the torque converter outer shell and configured to be connected to the crankshaft.
- the flex plate operates in a known manner to smooth the variations in drive torque from the internal combustion engine.
- the auxiliary drive unit can be for something other than the oil pump and could possibly also be just comprised of the drive shaft that is solely used for the RPS.
- the auxiliary drive is located on a side of the transmission housing opposite from a torque converter side, and the drive shaft extends through the transmission housing and the RPS is positioned on the drive shaft on the torque converter side of the transmission housing.
- the drive shaft can be driven with a chain and sprocket drive arrangement from the torque converter hub, or can be a direct gear drive.
- the RPS is preferably a rotary resolver or rotary encoder. Although any type of sensor can be used that is configured to sense rotary position.
- a transmission with an integrated hybrid drive includes a transmission housing and a torque converter rotatably mounted within the transmission housing.
- the torque converter including an outer shell and a pump hub.
- An E-motor is provided having a stator connected to the transmission housing, a rotor connected to the outer shell, and a controller.
- An oil pump is provided having a drive shaft that is driven by a connection to the torque converter pump hub.
- a RPS is located on the drive shaft and is configured to signal rotor position data to the controller.
- FIG. 1 is a schematic cross-sectional view through a transmission with an integrated hybrid drive according to one embodiment.
- FIG. 2 is a detailed view showing a first side of the transmission housing with an existing auxiliary drive area.
- FIG. 3 is a view showing the opposite side of the transmission housing from FIG. 2 with the position of a rotary position sensor.
- FIG. 4 is an enlarged detailed view taken from FIG. 3 .
- FIG. 1 schematically shows the transmission 10 in half cross-section while FIGS. 2-4 showed details of the transmission housing 12 .
- the transmission 10 includes a transmission housing 12 along with a torque converter 14 that is rotatably mounted within the transmission housing 12 .
- the torque converter 14 includes an outer shell 16 along with an impeller pump 18 that is configured to be drivingly connected to a crankshaft 20 of an associated internal combustion engine.
- a flex plate 22 is located between the crankshaft 20 and the outer shell 16 .
- the flex plate 22 can be of known construction and acts to smooth rotational torque fluctuation from the crankshaft 20 being input to the transmission 10 .
- the torque converter 14 further includes a turbine 24 is connected to an output shaft 26 of the torque converter 14 in order to transfer torque downstream along a driveline between the internal combustion engine and the driven wheels.
- An E-motor 30 is located within the transmission housing 12 .
- the E-motor 30 includes a stator 32 connected to the transmission housing 12 as well as a rotor 34 that is connected to the outer shell 16 of the torque converter 14 .
- a controller 36 is also provided for the E-motor 30 , and is schematically represented in FIG. 1 .
- An auxiliary drive unit such as an oil pump 40 , having a drive shaft 42 that is driven by a connection to the torque converter output shell 16 is provided. This is positioned in the auxiliary drive area 41 indicated in FIG. 2 on the transmission housing 12 .
- a rotor position sensor (RPS) 50 is provided on the drive shaft 42 and is configured to signal rotor position data to the controller 36 such that the E-motor 30 can be controlled in use.
- the oil pump 40 is located on a side 12 A of the transmission housing 12 that is opposite from a torque converter side 12 B of the transmission housing 12 .
- the drive shaft 4 extends through the transmission housing 12 and the rotor position sensor 50 is positioned on the torque converter side 12 B of the transmission housing 12 .
- One or more bearings 48 can be used to support the drive shaft 42 .
- the torque converter 14 further includes a torque converter pump hub 28 , and a chain drive 44 extends between the torque converter pump hub 28 and the drive shaft 42 .
- sprockets 45 , 46 are located on the torque converter pump hub 28 and the drive shaft 42 , respectively.
- Other types of drives, such as a direct gear drive could also be utilized in order to drive the driveshaft 42 directly from the torque converter pump hub 28 with little or no lash so that the position of the rotor 34 can be accurately determined.
- a drive ratio of the torque converter pump hub 28 to the drive shaft 42 is 1:1.
- other drive ratios such as 1:2 to 1:6, for example, could be used and the RPS 50 and/or the controller 36 can be configured and/or calibrated to take into account the drive ratio such that the position of the rotor 34 is accurately determined.
- the RPS 50 is mounted to the transmission housing 12 and a resolver housing 52 is mounted over the RPS 50 .
- the resolver housing 52 is sealed to the transmission housing 12 in order to provide a water-tight enclosure for the RPS 50 .
- a seal 54 can be utilized.
- an RTV sealant can be applied to the surfaces during installation.
- this arrangement allows the drive shaft 42 to be mounted parallel to an offset from the axis A of the torque converter 14 which allows for offset positioning of the RPS 50 relative to the axis A of the rotor 34 and the torque converter 14 .
- This allows for better space utilization and eliminates the need for a custom configured rotor position sensing arrangement in a co-axial position with the rotor 34 and the torque converter 14 , as was previously known.
- the present arrangement allows the use of an off-the-shelf position sensor to be used as the RPS 50 , which can be a known type of rotary resolver or rotary encoder.
- the auxiliary drive unit could be something other than oil pump 40 , and could also just be an offset drive shaft 42 that is driven by the torque converter 14 or the rotor 34
- one specific application where an E-motor 30 is being incorporated into an existing envelope of a transmission 10 takes advantage of the space previously assigned to the oil pump 40 as the auxiliary drive unit as well as the existing drive arrangement for the oil pump 40 , only requiring modification to the drive shaft 42 so that it is extended in order to accommodate the RPS 50 located within the bell housing 12 of the transmission.
- the resolver housing 52 is sealingly mounted over the RPS 50 to meet water-tight enclosure requirements for the particular application.
